Sharp fractions are obtained even after short sieving times. The AS 300 control is particularly designed for test sieves with a diameter of 305 mm (12″). Compared to sieves with a diameter of 200 mm, a 2.25 times higher sieving surface is available. Therefore, the average sieving times can be greatly reduced with the AS 300 control.

This increases the surface area of the dross, making it easier to separate the aluminum from the impurities during the next stage. Process: The ball mill is a cylindrical chamber filled with steel balls of varying sizes. As the chamber rotates, the balls tumble and crush the dross against the inner lining and against each other.
